Ok so, I probably shouldn't be looking, but I am. Man there are so many brands and variations out there for this upgrade, it's kind of daunting.
Ok in a nutshell, Kv stands for RPM's give or take, so the higher the Kv, the higher the RPM's? Is that like the higher the top end?
The lower the Kv, the lower the RPM's, more torque?

Plus the 3650 the front 4 numbers, sometimes associated with a letter or two. Is this is the can size? Bigger diameter, longer can size?

Is there a spreadsheet or more information for the RC car and or truck format, I found a considerable amount of information for drones and planes.

Any recommended combos, that work well with the Torment?

Looking at one of these, I realize it's not a castle or Hobbywing setup but I am not racing it, and do not care about top speed that I can't control.

Kv is the RPM per volt. Given whatever battery you use, you can then predict the approximate RPM the motor will run at max (assuming the motor is capable). The higher the Kv the lower the torque, generally.

Given your example of 3650 can size the 36 is the diameter is mm and the 50 is the length in mm.
 
Thanks X , I was seeing other combos not just the GoolRc ones, that show 3650, 3660, 3670, (these just mean the can is longer?) and a few as small as 2430.
Oh doh`, I just read that 2430 is for a 1/16-1/18 scale. Ok that clears that up.

I R learning all sorts of new stuff......:p
 
You're right on the can lengths. The longer the can the more torque.
And here comes the monkey wrench...
Higher kv does not mean less torque. It does mean higher rpms. If you take a 2850kv can, and gear it to have the same top speed as a 3800kv, you will have more torque with the 3800kv then the 2850kv. Now the reason that most think (as I did too), lower kv means more torque, is if you had the two motors on the same gearing, the lower kv will accelerate faster, but have less top speed. So it would appear to have more torque, but it actually doesn't. Now this doesn't mean get the highest kv motor you can find. You can go to high in kv, either to high of a kv for your voltage, or to high for your available gearing. And there is such a thing as too much torque. Hard to keep traction, which will lead to slower acceleration. And more broken parts. People who compete with crawlers generally use around 3300kv on 3s. I run a 3100kv on 3s with 2.8s on my ecx. I tried a 3900kv, but couldn't gear it down enough, and it would get hot rather quick. The 3800kv should be fine on 2s, but not 3s for long bashing sessions.
Enough rambling for me. If you are interested in learning more on kv, or everything about rc motors, there is a guy called John Robert Holmes who owns a rc motor company called homles hobbies, and has YouTube videos explaining everything you could imagine on motors, brushed and brushless. He's a crawler guy, but it's still the same motor theory. I haven't seen any, not a YouTube guy, hard for me to hear electronic voices, but I've read a lot that he's written.
 
I went with a Dynamite Tazer 3300kv 4 pole and dynamite programmable ESC. I tell you, the first run you do from switching over to brushless puts a massive smile on your face. Then you think why didn't I make the switch sooner.

The reason I went with this setup is because I wanted a bit more torque and less rpm (to make things more manageable) and also I copied the same setup as in the stock ECX brushless torment. I did upgrade to hot racing steel drive shafts.

Where did you get them from - LHM or online?
